Metabolism of oxygen by cells generates potentially deleterious reactive oxygen species (ROS). Under normal conditions the rate and magnitude of oxidant formation is balanced by the rate of oxidant elimination. However, an imbalance between prooxidants and antioxidants results in oxidative stress, which is the pathogenic outcome of oxidant overproduction that overwhelms the cellular antioxidant...

Diabetes is a disease correlated with the damage of b-pancreatic cells, due to increasing number free-radicals in body, causing body failed produce insulin normal degree, cannot function effectively. In general, diabetic patients suffered from lipid metabolism distortion that would increase total cholesterol level imbalance between and endogenous antioxidants. Purple sweet potato has high antio...

Antioxidants have an important role in control and prevention of dangerous diseases like cancers, but instability and high solubility of the antioxidants are <span style="font-size: 11pt; color: #00000...

background: prescription of antioxidants might increase the quality of sperm parameters and improve the rate of pregnancy in obese people who suffer from infertility. therefore, the present study investigated protective effects of vitamin a, e and astaxanthin on sperm parameters and seminiferous tubules epithelium in high-fat diet model. methods: thirty-six numbers of 3 months old albino wistar...

BACKGROUND: Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycaemia. Increased oxidative stress and decreased antioxidant levels are the leading cause of diabetes and diabetic complications. So it is felt that supplementation of antioxidants may be useful in controlling the glucose levels and to postpone the occurrence of diabetic complications. The objective of our st...

O xidation processes are essential in normal cell metabolism. Free radicals, i.e. reactive oxygen and nitrogen compounds, are formed continuously. They participate in metabolic and cell signalling pathways, in spite of their potentially deleterious effects. A system of endogenous anti-oxidative compounds and systems operates to control strictly the concentrations and actions of free radicals. D...

Normal 0 false false false MicrosoftInternetExplorer4 The present study was carried out to determine the effect of hydroalcoholic extract of Tylophora indica (HETI) on experimentally-induced myocardial infarction (MI) in rats. Albino rats were treated with HETI at doses of 100 mg/kg, (HETI-100) or 200 mg/kg (HET...

Essential oils possessing antioxidant characteristics have acquired broad interest as an alternative to synthetic food antioxidants like butylated hydroxytoluene (BHT). In this study, mānuka (with 5, 25 and 40% triketone content) (MO), rosemary (RO) kānuka (KO) were characterised screened through DPPH (2,2-diphenyl-1-picrylhydrazyl) FRAP (Ferric radical absorbing power) assays for their efficac...

OBJECTIVES To assess the effect of cigarette smoking on lipid peroxidation induced oxidative stress, antioxidants, uric acid and blood sugar in normal subjects. METHODS The study included 61 normal subjects with regular smoking habit and 57 never-smokers normal subjects matched in respect to socio-economic status, age and BMI. Information regarding smoking habit and other personal details wer...
